Source Naturals L-Tryptophan 500 mg - 120 Capsules
The essential amino acid l-tryptophan helps support relaxation, restful sleep, and positive mood. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep-wake cycles. l-Tryptophan also supports immune functions because it is the body�s precursor to the kynurenines that regulate immunity. If needed, l-tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system.
- 1 capsule three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 capsules before bed.
